Key takeaways
- Alt text is supported when scheduling with SkedCast on Bluesky, Facebook, Instagram, LinkedIn, and Threads, plus X.
- It is not currently supported through SkedCast on TikTok, YouTube, Pinterest, or Telegram — on Pinterest specifically, the platform itself supports alt text even though SkedCast’s adapter does not send it yet.
- Where it’s unsupported, add alt text directly in the platform’s own app after a post publishes, if the platform offers that.
Alt text for scheduled social media posts: where SkedCast supports alt text today
The composer offers an alt-text field, and SkedCast’s adapter sends it to the platform, on each of these:
- X (Twitter) — per-image alt text
- LinkedIn — per-image alt text
- Instagram — per-image and per-video alt text
- Facebook — per-image alt text
- Threads — per-image alt text
- Bluesky — per-image alt text
Where it isn’t supported yet
On the remaining platforms, SkedCast’s composer does not offer an alt-text field when scheduling a post:
- TikTok — TikTok’s Content Posting API has no alt-text field for scheduled posts.
- YouTube — the Data API used for uploads has no image alt-text concept (YouTube videos don’t carry image alt text the way a feed image post does).
- Pinterest — Pinterest’s own Pin editor supports alt text, but SkedCast’s adapter does not send it through the API yet; add it manually in Pinterest after the Pin publishes if you need it.
- Telegram — the Bot API SkedCast publishes through has no alt-text field on photo messages.

FAQ
- Can I add alt text when scheduling an Instagram post with SkedCast?
- Yes — Instagram is one of the platforms where SkedCast’s composer offers a real alt-text field per image or video, and it’s sent through to Instagram at publish time.
- Does Pinterest support alt text at all?
- Yes, Pinterest’s own Pin editor supports alt text — but SkedCast doesn’t send it through the API when scheduling a Pin yet. If you need alt text on a specific Pin, add it directly in Pinterest after it publishes.
